IMPROVEMENT IN EXTENSION-TABLE SLIDES.

Specification forming part of Letters Patent No. E 65,642, dated July 13, 1R75; application le J une 1, 1875. t

To all whom 'it may concern:

Be it known that l, L. N. Jamestown, in the county of Chautauqua and State of New York, have invented certain new and useful Improvements in EXtension-Tiihle Slides, and l do hereby declare that the following is a fulll clear, and exact description thereof', reference heing had to the accompanying drawings, and to the letters of reference marked thereon, which form part of this specitication.

The nature of my invention consists in the construction and arrangement ot'an extensiontable slide, as will he hereinafter more fully set forth.

ln order to enable others skilled in the art to which my invention appertains to make and use-the saine, l will now proceed to describe its construction and opera-tion, referring to the annexed drawing, in which- Figure l is aplan view of my improved eX- tension-tahle slide. Fig. 2 is a side view thereof; and Fig. 3 is a. section through the line .r ar, Fig. l.

A A represent two or more sections, joined together in the following manner: Each section A is grooved through the side with one or more straight g'rooves, b, which are parallel with each other when the sections are placed together. In these grooves are placed iron tongues c c, of sufficient width to till each groove, and of the right height to form the lap ot' the sections when the slide is drawn out. These tongues are not fastened in the grooves, hut are placed loosely therein, and

WILLARD, ot'

are always in the right place when the slide is drawn out to give the necessary strength. The grooves b b are not cut through the entire length, but are left closed at either end, for the purpose of making the stops x which prevent the slides from coming out beyond the lap. B B represent hooks, made in the form of hat staples, as shown. These hooks are driven tightly into mortises in one section,and run in grooves d d in the opposite section, and are simply tor the purpose of holding the sections together as they run on the tongues in the side grooves, thereby giving the requisite strength and stiffness to the slides.

This extension-table slide is simple in construction, cheap to manufacture, and yet durable and easy of operation, and not liable to get. out of order.

Having thus fully described my invention, p

what I claim as new, and desire to secure by Letters Patent, is

In combination with the section A A, having the side grooves b b, stops .r 5v, and the tongues a a, sliding loosely in the grooves b b,-
